but admit the fact that Bitcoin is not created in purpose of Asset or Holding
It is deemed an asset now because it's volatility/liquidity is still very high, The original intention for it as an alternative currency will come into play when its liquidity has reduced, and almost all the mineable bitcoin has been mined. The value will by then become stable and the original intention the creators have for it will materialize.
I don't see a reason for this to lead to price stability. If the world is still denominated in fiat currencies, then chasing the limited supply of bitcoin (assuming the store of value premise is still relevant) will mean the price will still be based on speculation and thus likely suffer from high volatility. This is what keeps it from being a useful currency. Also, with the elimination of block rewards, fees are likely to go up to subsidize the cost of mining, further reducing any utility as a currency.
As time goes by, not only will some see it as currency, it may not meet some standards, but JP Morgan banks are already accepting it despite JP Morgan going very against BTC, some economists, banks and Governments will never accept volatility, it is obvious, they will go to safe assets and stocks, such as Gold, among others.
Crypto currencies can never be of a nature like fiat money, their protocols are very different, this without mentioning that crypto is usually deflationary in nature while fiat money is inflationary in nature and its endorsements such as gold is simply a mirage. I think that the purpose of BTC still holds and with much more force as time goes on.If we take into account the examples of countries like "El Salvador" and possibly Paraguay, it changes every point of view of those who are enemies of BTC.
